how the library is not like a bookstore, part eleventyteen

I enjoy the Stay Free! blog a lot. Today Carrie has a blurb that includes information from a New York Times story about big box bookstores like Barnes & Noble determining display space by how much they get paid by the publisher. I had always sort of cited this as something I knew, but I was never sure how I knew it. Carries adds this tidbit with request for authoritative citation, anyone know?

In fact, a label rep once told me that Tower makes more money from selling in-store display space and other co-promotions than from selling CDs themselves. I find that a little hard to believe, but if anyone has real, compelling numbers on this, I’d be glad to share them.
